is there a difference from oem to aftermarket in the beam pattern I have some ones I ordered off ebay 2 years ago and put them back in the car with the halogen bulbs and notice the beam pattern on the road is horrible if so I was going to go to get another set of oem headlights or order some I have to redo my retro's soon (install new halos , reaim ) and have to put stocks back in ?
